A B S T R A C T PREPARTION OF SPHERICAL MAGNESIUM ALKOXIDE PARTICLES A process for preparing spherical particles of a compound with the general formula Mg(OR)2-a(OR')a in which R is an alkyl group with from 2 to 8 carbon atoms, R' is an alkyl group with from 1 to 7 carbon atoms and a is a number of from 0 to 0.5, which comprises preparing a homogeneous solution of a compound Mg(OR)2 in an aliphatic alcohol with the general formula R'OH spray-drying the solution at a temperature of from 15 to 85 °C, suspending the spray-dried solid particles in an aliphatic alcohol with the formula ROH in which R is the same alkyl group as present in the said compound Mg(OR)2 heating the suspension in order to remove an alcohol with the formula R'OH from the liquid phase by distillation and separating the solid particles from the liquid phase.
